In a commanding performance, the Los Angeles Chargers defeated the Seattle Seahawks 40-13 in Week 4 of the 2026 season. This victory not only solidifies the Chargers' position in the playoff race but also sends a clear message about their offensive firepower. Chargers quarterback Justin Herbert stole the show with an impressive four touchdown passes, showcasing his ability to orchestrate a high-octane offense. Seattle's Sam Darnold put up a respectable 300 passing yards, but the Chargers' offensive depth proved too much to handle. Cooper Kupp emerged as a standout for the Seahawks, racking up 152 receiving yards, but it was not enough to keep pace with the relentless Chargers attack. Defensively, the Chargers made their mark with a crucial interception from Derwin James Jr., which shifted the momentum in their favor. Although Bud Clark led Seattle with nine total tackles and DeMarcus Lawrence added a sack, the Chargers' defense effectively stifled the Seahawks' scoring opportunities when it mattered most. The game's turning point came in the second quarter when the Chargers forced a turnover, allowing them to capitalize and extend their lead, sealing the outcome well before the final whistle.
